I guess I mostly agree (I don't think it's that important and it sometimes
makes sense to me to get to two different points (for the same display
position) depending on how I reach this display position.  This is
typically the case when the invisible text is non-sticky at both ends).

The whole point of my patch is indeed to avoid such situations where one
display position can correspond to more than one point value.
Your invisible+intangible code had the same goal but only works for
intangible text, whereas mine works for all invisible text.
